Just tested your fork and everything works great. True color really needs to be officially supported.

You should create a pull request.

That would be great. We need to preserve backward compatibility though, and use true colors only if vim is using true colors.

i still do not know what i'm doing but this seams to work.

but there might still be problems with non airline themes because that's the only thing i tested.

Any chance that this could be merged in? It would be a useful feature.
